Hi guys
Noobie here, trying to understand Assembly programming.
I'm stuck trying to figure how assembly manage strings and variables.
I succeeded creating a Script to capture keystrokes and display them in the screen.
Now how do I save these keystrokes (letters/numbers) in a "variable", keep it in memory and display the text later?
Thanks

You just write the bytes to memory somewhere and read it from the same location to print it. Most assemblers have a keyword to reserve some space without storing anything at assemble-time. This can be used to reserve space for that string in memory. This is an example of a common way to reserve 8 bytes: ds.b 8 |
